Bosch Power Tools

f

The arbour size of wheels and flanges must 
properly fit the spindle of the power tool. 

Wheels and flanges with arbour holes that do 
not match the mounting hardware of the 
power tool will run out of balance, vibrate ex-
cessively and may cause loss of control.

f

Do not use damaged wheels. Before each 
use, inspect the wheels for chips and 
cracks. If power tool or wheel is dropped, 
inspect for damage or install an undamaged 
wheel. After inspecting and installing the 
wheel, position yourself and bystanders 
away from the plane of the rotating wheel 
and run the power tool at maximum no load 
speed for one minute. 

Damaged wheels will 

normally break apart during this test time.

f

Wear personal protective equipment. De-
pending on application, use face shield, safe-
ty goggles or safety glasses. As appropriate, 
wear dust mask, hearing protectors, gloves 
and workshop apron capable of stopping 
small abrasive or workpiece fragments. 

The 

eye protection must be capable of stopping 
flying debris generated by various operations. 
The dust mask or respirator must be capable 
of filtrating particles generated by your opera-
tion. Prolonged exposure to high intensity 
noise may cause hearing loss.

f

Keep bystanders a safe distance away from 
the work area. Anyone entering the work ar-
ea must wear personal protective equip-
ment. 

Fragments of the workpiece or of bro-

ken cutting discs may fly away and cause 
injury beyond the immediate area of opera-
tion.

f

Hold power tool by insulated gripping sur-
faces only, when performing an operation 
where the cutting accessory may contact 
hidden wiring or its own cord. 

Cutting ac-

cessory contacting a “live” wire may make ex-
posed metal parts of the power tool “live” 
and shock the operator.

f

Keep the mains cable away from rotating 
application tools. 

When losing control over 

the machine, the mains cable can be cut 
through or get caught, and your hand or arm 
can come in contact with the rotating cutting 
disc.

f

Never lay the power tool down until the ac-
cessory has come to a complete stop. 

The 

spinning cutting disc may grab the surface 
and pull the power tool out of your control.

f

Do not run the power tool while carrying it 
at your side. 

Accidental contact with the 

spinning accessory could snag your clothing, 
pulling the accessory into your body.

f

Regularly clean the power tool’s air vents.  

The motor’s fan will draw the dust inside the 
housing and excessive accumulation of pow-
dered metal may cause electrical hazards.

f

Do not operate the power tool near flamma-
ble materials. 

Sparks could ignite these ma-

terials.

f

Do not use accessories that require liquid 
coolants. 

Using water or other liquid cool-

ants may result in electrocution or shock.

Kickback and related warnings

f

Kickback is the sudden reaction to a pinched 
or snagged rotating cutting disc. Pinching or 
snagging causes rapid stalling of the rotating 
cutting disc. This causes an uncontrolled 
power tool to be forced in the direction op-
posite of the cutting disc’s rotation direction 
at the point of binding.
For example, if a grinding disc is snagged or 
pinched in the workpiece, the edge of the 
grinding disc that is entering into the work-
piece can be caught, causing the grinding 
disc to break out or cause kickback. The 
grinding disc may either jump toward or 
away from the operator, depending on the di-
rection of the wheel at the point of blocking. 
Grinding discs can also break under these 
conditions.
Kickback is the result of power tool misuse 
or incorrect operating procedures. It can be 
avoided by taking proper precautions as de-
scribed below.
